Best bet is probably something like Obsidian/1writer/typora, pasting into plain text files synced via Dropbox or similar.
There’ll be a few seconds delay while things sync, obvs, but shouldn’t be TOO unreasonable.
Or, get the MS Remote Desktop app on the ipad, I *think* if you copy stuff from a different app on the ipad it’ll paste it into whatever is open on the PC. I reserve the right to be wrong though.
